Try the spirits whether they are of God (1 Jn. 4:1) “…and Believe not every spirit”. All people are commanded to examine all spiritual things with our critical faculties to see if the Word of God being presented. There are evil spirits that can produce paranormal phenomena therefore we are exhorted by the Scripture to prove the spirits or test the spirits; prove all things; hold fast only to that which is good.
Proving all things requires the use of our reasoning and understanding but we cannot rely only on our intellect. We cannot be swayed by our inward feelings but we can trust the illumination and guidance of the Holy Ghost. Moreover, the greatest principle concerning the testing of spirits are the Scriptures themselves because the Bible is the Truth. (1 Cor. 12:3), “Wherefore I give you to understand, that no man speaking by the Spirit God calleth Jesus accused: and that no man can say that Jesus is the Lord but by the Holy Ghost”. The is the supreme test of discerning spiritual things.

John, said the same thing: “Hereby know ye the spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: and every spirit that confesseth not that Jesus Christ is come in the flesh is not of God,” (l Jn. 4:23).
